Selecting cells and rows in the Spark DataGrid control

This question was posted in response to the following article: http://help.adobe.com/en_US/flex/using/WS0ab2a460655f2dc3-427f401412c60d04dca-7ff8.html

"Note: While the selectedCells, selectedIndices, and selectedItems properties are all writable, Adobe recommends that you use methods of the DataGrid to change selection programmatically."
OK.. So how do I programmatically select multiple items?
The setSelectedIndex method will only add a single item.
I have tried to ''push" an index onto the selectedIndicies but that won't work either...
Please help me.. this is driving me nuts...

Selecting an entire row with the help of Checkbox

Hi and Evening to Everybody,
I have a Scenario where i need to select an entire row using the check box. Let me first define the Situation. I created a Simple Sql-report where the first column is a Simple Checkbox and the second column is a display only name and followed by the rest 5 columns as a checkbox.
my table structure is :
**create table satt (SELECT_ALL VARCHAR2(10), Name VARCHAR2(50), Object1 VARCHAR2(10), Object2 VARCHAR2(10), Object3 VARCHAR2(10), Object4 VARCHAR2(10), Object5 VARCHAR2(10));**
Now i had a requirement where i need to Check All or Uncheck All Checkbox by clicking SELECT_ALL column header and i made it using
simple java-script :
"<input type="Checkbox" onclick="$f_CheckFirstColumn(this)">"
Now i need to Check all checkbox in a row by clicking any of the SELECT_ALL check boxes. (Say i have 5 checkboxes in SELECT_ALL column and if i click 3rd checkbox... i need the entire 3rd row checkbox to be checked on click of that 3rd check box).
I hope i was clear with my question. i did my best. Please help me out with this... Im eagerly lookin for the solutions.
Thanks & Regards,
- The Beginner.

There is no row order in relational tables unless ORDER BY is used, so there is no way to decide if 3 Mathematics belongs to 100 or to 200.
SY.That's not how I interpretted it. I thought he was saying that in the first row column B has the value:
'1 Physics'||chr(10)||'2 Chemistry'||chr(10)||'3 Mathematics'
in which case something like this would work
select a,replace(b,chr(10),chr(10)||a||' ') from table;

Playing with the spark datagrid

I'm Playing with the spark datagrid and have a column set up like so:
<GridColumn width="140" headerText="Margin" headerText.editMode="Margin (editing)" dataField="margin" editable="false" editable.editMode="true" itemRenderer="gridColumnRenderer" >
           </GridColumn>
I would like the item render to change colour based on the state of the outerDocuent, is this possible?
I tried this but can't get to the outerdocument
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
                xmlns:s="library://ns.adobe.com/flex/spark"
                xmlns:mx="library://ns.adobe.com/flex/mx"
                autoDrawBackground="true">
    <s:Label text="{data.margin}" backgroundColor="{   outerDocument.currentState =='editMode'?0xffffff:0xdddddd}"/>
</s:ItemRenderer>

I believe you will need to use GridItemRenderer instead of ItemRenderer as your base class for renderers in the spark DataGrid. Does it work if you change to that?

Urgent : how to select the rows in the ALV Grid Control

How to select the rows in the ALV Grid control,
I am facing the situation where i need to select the row/rows in the Grid control and then to lock the entries,
If anyone have the solution please help me out
<b>Its very Urgent</b>

Hi Bharath,
Go through this hope u can understand.
SEL_MODE. Selection mode, determines how rows can be selected. Can have the following values:
A Multiple columns, multiple rows with selection buttons.
B Simple selection, listbox, Single row/column
C Multiple rows without buttons
D Multiple rows with buttons and select all ICON
Setting and getting selected rows (Columns) and read line contents
You can read which rows of the grid that has been selected, and dynamic select rows of the grid using methods get_selected_rows and set_selected_rows. There are similar methods for columns.
Note that the grid table always has the rows in the same sequence as displayed in the grid, thus you can use the index of the selected row(s) to read the information in the rows from the table. In the examples below the grid table is named gi_sflight.
Data declaration:
DATA:
Internal table for indexes of selected rows
gi_index_rows TYPE lvc_t_row,
Information about 1 row
g_selected_row LIKE lvc_s_row.
Example 1: Reading index of selected row(s) and using it to read the grid table
CALL METHOD go_grid->get_selected_rows
    IMPORTING
      et_index_rows = gi_index_rows.
DESCRIBE TABLE gi_index_rows LINES l_lines.
IF l_lines = 0.
    CALL FUNCTION 'POPUP_TO_DISPLAY_TEXT'
         EXPORTING
              textline1 = 'You must choose a valid line'.
    EXIT.
ENDIF.
LOOP AT gi_index_rows INTO g_selected_row.
     READ TABLE gi_sflight INDEX g_selected_row-index INTO g_wa_sflight.
    ENDIF.
ENDLOOP.
Example 2: Set selected row(s).
DESCRIBE TABLE gi_index_rows LINES l_lines.
IF l_lines > 0.
    CALL METHOD go_grid->set_selected_rows
        exporting
          it_index_rows = gi_index_rows.
ENDIF.

Hi there, I'll tweak your code a little bit to something like this:

Item availability for selected items and directly create the delivery

Hi All,
For a very big sales order ..lets say having 700 line items ...is there any convenient way to create the delivery for selected items ..e.g. 30-40 line items rather going and selecting the line items then doing the item availability.
do you have any LSMW format by which we can do the item availability for selected items and directly create the delivery.
kindly Guide me..
With Regards
Azeez.Mohd

Hi ,
There is no stand way of doing it . You need to take help of abaper to do this :
1. Create a t code where if you give sale order number , it displays a report with all the items with a check box near to it as we see in SE16 .
2. This report could be best in ALV form where users can do "ctr+f" and search only the required materials then select those lines and press a button on the top of report .
3. Once the button is pressed , program will run vL01n ( create delv in backgrnd) in a BDC form . At time of delev creating , the bdc program in backgrnd uses only those items which were selected by user and not the other items .
4. Program will create a delv using a BDC in background and return the delv number for user to view tht.
U can also try using FM : RV_DELIVERY_CREATE to create delv in backgrnd after user selection if BDC is getting tricky.
Hopefully ,this shuld work and will be a easy process for the customers.
Let us know the outcome .. .
B O L ..
Hope this Helps !!!

Select, Copy and Paste text - the iPhone can't do that either???

Select, Copy and Paste text - the iPhone can't do that either??? OK, this is pretty lame...the iPhone does not allow you to select, copy or paste text in SMS, Notes, Safari or Mail. Is this just a oversight on the part of Apple?

Apple left out a LOT of basic functionality from the iPhone. I think they believe that the 'sexiness factor' will far outweigh the need for functionality in getting this phone to sell. For the most part they were right. Now that most of us have realized what this phone cannot do, and that the honeymoon is over (well, for the most part) I hope that Apple will do include some of that basic functionality in future updates. I also hope that the 3G phone is not the answer to this because that will leave out a lot of users who want these basic features but who dont really want 3G.

Hi,
It seems this is a Microsoft related. You are referring on how to set JPG Image in Photoshop Elements by default. You may try visiting Microsoft's Support page http://support.microsoft.com/ for you to get the correct information/help you need.
Thank you.

What is the point of [Bindable("selectionChange")] in parts of the spark datagrid class?

I dont understand the point of this code in the spark datagrid class:
what is the point of this:
    [Bindable("selectionChange")]
     [Bindable("valueCommit")]
     [Inspectable(category="General", defaultValue="null")]
in
    // selectedItem
    [Bindable("selectionChange")]
    [Bindable("valueCommit")]
    [Inspectable(category="General", defaultValue="null")]
     * @copy spark.components.Grid#selectedItem
     * @default null
     * @langversion 3.0
     * @playerversion Flash 10
     * @playerversion AIR 2.5
     * @productversion Flex 4.5
    public function get selectedItem():Object
        if (grid)
            return grid.selectedItem;
        return (dataProvider && (selectedIndex > 0)) ?
            dataProvider.getItemAt(selectedIndex) : undefined;
     * @private
    public function set selectedItem(value:Object):void
        if (grid)
            grid.selectedItem = value;
        else
            var f:Function = function(g:Grid):void
                g.selectedItem = value;
            deferredGridOperations.push(f);

Anything that is binding to selectedItem will go get the value again when either of those events fires.

How to get the current selected column and row

Hi,
A difficult one, how do i know which column (and row would also be nice) of a JTable is selected?
e.g.
I have a JButton which is called "Edit" when i select a cell in the JTable and click the button "Edit" a new window must be visible as a form where the user can edit the a part of a row.
Then the column which was selected in the JTable must be given (so i need to know current column) and then i want the TextField (the one needed to be edited) be active with requestFocus(). So it would be
pricetextfield.requestFocus();
Problem now is that i have to click every time in the window the JTextField which was selected in the JTable. I have chosen for this way of editing because my application is multi-user and it would be too difficult for me when everybody did editing directly (catch signals, reload data, etc.).
My question is how do I know the current column and the current row in a JTable?

I'm not sure what your mean by the "current" row or column, but the following utility methods return
which row and column have focus within the JTable.
public static int getFocusRow(JTable table) {
return table.getSelectionModel().getLeadSelectionIndex();
public static int getFocusColumn(JTable table) {
return table.getColumnModel().getSelectionModel().getLeadSelectionIndex();
}

Merge multiple cells and rows

Hello,
I am trying to merge multiple cells and have found that I can do thi easily by selecting the adjancent row cells and using the TABLE - MERGE CELLS command. However, If I want to apply the same merge to multiple rows, I can find noquick way to do this other than selecting each set of cells and using the TABLE - MERGE CELLS command each time. Here is an example of what I want to do:
Here is the Numbers spreadsheet as normal:
Here is cell B2 and C2 merged:
Now what I want to do is the same process for rows 3 to 10. However, when I try to select the section and use the TABLE - MERGE CELLS command, I get on large cell rather than split rows of merged cells as seen below:
Any idea how I can or if I can accomplish this task?
Thanks in advance,

You may also use this script :
--{code}
--[SCRIPT merge_row_by_row]
Enregistrer le script en tant que Script : merge_row_by_row.scpt
déplacer le fichier ainsi créé dans le dossier
<VolumeDeDémarrage>:Utilisateurs:<votreCompte>:Bibliothèque:Scripts:Applications :Numbers:
Il vous faudra peut-être créer le dossier Numbers et peut-être même le dossier Applications.
Sélectionner le bloc de cellules à traiter.
Aller au menu Scripts , choisir Numbers puis choisir “merge_row_by_row”
Le script fusionne les cellules de chaque ligne appartenant à la sélection.
--=====
L’aide du Finder explique:
L’Utilitaire AppleScript permet d’activer le Menu des scripts :
Ouvrez l’Utilitaire AppleScript situé dans le dossier Applications/AppleScript.
Cochez la case “Afficher le menu des scripts dans la barre de menus”.
Sous 10.6.x,
aller dans le panneau “Général” du dialogue Préférences de l’Éditeur Applescript
puis cocher la case “Afficher le menu des scripts dans la barre des menus”.
--=====
Save the script as a Script: merge_row_by_row.scpt
Move the newly created file into the folder:
<startup Volume>:Users:<yourAccount>:Library:Scripts:Applications:Numbers:
Maybe you would have to create the folder Numbers and even the folder Applications by yourself.
Select the range of cells to treat
Go to the Scripts Menu, choose Numbers, then choose “merge_row_by_row”
The script merge the cells of every row included in the selection.
--=====
The Finder’s Help explains:
To make the Script menu appear:
Open the AppleScript utility located in Applications/AppleScript.
Select the “Show Script Menu in menu bar” checkbox.
Under 10.6.x,
go to the General panel of AppleScript Editor’s Preferences dialog box
and check the “Show Script menu in menu bar” option.
